Seems the program can be used with the PASE joystick interface.

I was at school with John Sandham when he wrote this game. He was very good at maths and had researched 3d calculations. This was the first game that made use of this knowledge. I think he also wrote a game called Chaos Chasm (listed on here). I remember that we couldn't afford BBC micros at school at that time. The Oric's had the same processor and hence assembly code.

Only just discovered this game today. The 3D effect is pretty cool to look at, but I found the game extremely difficult to play. Awkward keys do not help either, and add to that the fact that I am not much of a gamer anyway.
Loki did show me that it would be possible to create a game like Deathchase (play it on the Spectrum and love it) on the Oric. Least in Deathchase you don't have up and down as well as left, right & forward.
